The latest Lenovo P14s I have running Arch/sway has a crazy long battery life as well. It idles at 3.4W with wifi on. Writing code with an editor and all the fancy LSPS/plugins pushes me to 4W. I can get more than a full days worth of work on a single charge if I'm not doing anything compute heavy.
That said, it's not out of box like a Macbook.
It's a Intel(R) Core(TM) Ultra 7 155H. And as far as power is concerned, spending some time fiddling with tlp will get you a good chunk of the way there. Playing around with different DEs will give different results. Sway is my preference, it's my favorite and has the lowest power footprint. Blacklisting drivers, tuning sysctls and hardware helps as well.
I'm almost never CPU constrained, so I tend to have everything idled down as much as possible.
Edit: and just for context, opening firefox and browsing the web right now has me at 9W.
Good to know. I’m looking to transition into a Linux laptop setup and have been looking into power efficient setups.
What processor do you have?
